SHOCK-ABSORBER FOR VEHICLES.

rl neation filed. December is, 1911. Serial No. 666,472.

To all whom it may concern:

Be it known that I, HENRY ALLEN DAL- LEY, a citizen of the United States,'residing at Ardmore, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Shock-Absorbers for Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art. to which it appertains to make and use the same.

My invention relates to an improved shock absorber for vehicles, and it consists in the constructions, combinations and arrangements hereinafter described and claimed. 7

An object of my invention is to provide an improved shock absorber adapted to eliminate all excessive and injurious shocks and jars, thereby providing a steady riding vehicle and minimizing the wear.

A further object of my invention is to provide a strong and compact shock absorber adapted for ready use with standard types of spring-suspemled vehicles, which will relieve the spring-suspcnsion from abnormal stress..and constitute an etlicientbutter for preventing troublesome rebound ot the said gear under all practical conditions.

In the accompanying drawings forming a part of this application and in which corresponding reference symbols indicate similar parts in the several views :-Figure l is an elevation, illustrating one embodiment of my invention; Fig. 2 is a perspective view of the bearing disk and its engaging-seat shown in Fig. 1; Fig. 3 is a plan of the upper open link; Fig. t is a similar view'of the bifurcated lower link; and, Fig. 5 is a detail section on the line of" Fig. 1.

Referring to the drawings:-1 indicates the legs of an open link provided with a bearing 2 in which is pivolally mounted the head 3 of a tension rod 4. A lower link Specification of Letters 2ateni.

5 is provided with a. head 6 pivotally connected to the end 7 of the said link 1, and

provided with a cup 8 having an axial open-- yicldingly resist relative swing of said links about their pivotal connection. The free end of the link 1 is pivoted at 18 toany 'usual type of axle spring, such as a leaf spring 19 secured in the usual manner to the axle. The free end of, the lower link 5 is pivotally connected at 20 to either a spring or a bracket 21 secured to the vehicle body. It will be noted that in my improved construction the shock absorbing device isadapted to be inserted in series in any usual spring suspension gear, and that the forces are applied thereto in such manner that the spiral compensating spring 15 has an initial tension greater than that of the axle spring 19. This provides an efficient construction adapted to relieve the parts from excessive shocks and strains under all practical con ditions. v i A I have illustrated preferred and satisfactory construction, but changes could be made within the spirit and scope of my invention.

I claim 4 1. A shock absorber for spring-suspended vehicles, comprising a pair of links pivoted together at one end, means for pivotally connecting the free ends of said pivoted links to the vehicle body and axle spring res ectively, a rod pivoted to one of said lints, and a spring confined on said rod against the other of Sillti links.

A shock absorber for spring-suspended of-said links, and a spring confined between vehicles, comprising a pair of links pivoted said stop and seat. 10 together at one end, means for pivot'ally con- In testimony whereof, I aflix my signaneeting the free ends of said pivoted links tnre, in presence of two witnesses.
